I agree with you that it's ugly, but it's the way other people do it when they absolutely need to do it there. Most often, the only reason to do that on their load balancer is just to get rid of a server which was dedicated to that, since the LB happens to be able to do that too.

Haproxy's goal is not (and has never been) to take this part of the job which normally ought to be the application's job. But you know how users are, if they can do it, they will do it ;-)

If you need more complex redirects, be aware that many people like to combine haproxy+nginx on the same host and use nginx for the tricks that are more application-level, as it is more flexible. That may be an option to consider before your reqrep/redirect rules become unmanageable ;-)
